Emergency contraception and breast-feeding

· Trent Medicines Information Service

If emergency contraception is required, breastfeeding women can be advised of the following:

  • A single dose of 1.5mg levonorgestrel is licensed to be taken within 72 hours (3 days) of unprotected intercourse or contraceptive failure. No restriction on breastfeeding is required.
  • A single dose of 30mg ulipristal acetate is licensed to be taken within 120 hours (5 days) after unprotected intercourse or contraceptive failure. Although no restriction on breastfeeding is required, due to lack of data, ulipristal would not be the preferred emergency hormonal contraceptive method.
  • A copper intra-uterine device can be inserted up to 120 hours (5 days) after unprotected intercourse or contraceptive failure. If intercourse has occurred more than 5 days previously, the device can still be inserted up to 5 days after the earliest likely calculated ovulation. No restriction on breastfeeding is required.
